Drilling machine consists of a steel frame where no. 26 drilling chucks are placed and two conveyors for loading and unloading.
Able to produce holes on flexible expanded pu mattresses and pillows with plane surface, vertically relating to the table.
In case of drilling foam sheets loaded by bobbin, the work program can be continuously repeated by observing the gap between one drilling program and the next one.
Not built for latex because this material is just produced with holes inside; built just to produce holes in foam (less expensive) by using drilling tips 6mm/28mm diam. (customer can choose the hole diam.), and moreover, this machine does not need steel mold to be drilled.
Minimum foam sheet thickness is 10mm and the machine does not drill latex.
Machine can accommodate a 2200mm wide mattress.

Net weight: 2300 kg.
Working space: 4375 x 3780 h 2204 mm.
High productivity as the result of one line of 26 drills (3 seconds to perform 1 drilling line along 2200mm).
Min. 80mm between holes (it’s wrong: 80mm is the space between drilling chucks but thanks to the lateral movement of thrust yoke the holes can be 10mm distance).
Operation And Control
In order to avoid that the mattress moves during working cycle, a manually adjusting little roller device is placed on the material to be holed.
The foam is cored by the core drill, ejected by an air jet and evacuated by means of a conveyor belt.
The chucks supported thrust yoke moves lateral (y axis) and vertical (z axis).
It’s possible to program both movements: the lateral movement of thrust yoke (y axis) up to 100mm (in this case we obtain two or more series of holes in the same line (y pitch) and conveyor movement (x pitch) with infinity variable increments. The min. distance between holes is 10mm.
It’s also possible to program both straight drilling and crossed drilling.
The machine is controlled by 4 axis and its movements are controlled by plc.
The keyboard is equipped with a multifunction control device where working data are loaded.
A graphical window with alarm for wrong input helps operator to check the holes position.
The multi-function control includes alarms diagnostic.
The machine is equipped with a lubricating system device for the drills.
